“…Compared to the micro-sized solid-phase extraction support materials, magnetic nanoparticles have a high surface area and strong magnetism, therefore they are more suitable to construct magnetic solid phase extraction platform2526. The magnetic nanomaterials (such as iron oxide magnetic nanoparticles) and magnetic composite materials (such as magnetic carbon nanotubes, magnetic graphene oxide) have been systematically compared in our group.…”

Simple, accurate and high-throughput pretreatment method would facilitate large-scale studies of trace analysis in complex samples. Magnetic mixed hemimicelles solid-phase extraction has the power to become a key pretreatment method in biological, environmental and clinical research. However, lacking of experimental predictability and unsharpness of extraction mechanism limit the development of this promising method. Herein, this work tries to establish theoretical-based experimental designs for extraction of trace analytes from complex samples using magnetic mixed hemimicelles solid-phase extraction. We selected three categories and six sub-types of compounds for systematic comparative study of extraction mechanism, and comprehensively illustrated the roles of different force (hydrophobic interaction, π-π stacking interactions, hydrogen-bonding interaction, electrostatic interaction) for the first time. What’s more, the application guidelines for supporting materials, surfactants and sample matrix were also summarized. The extraction mechanism and platform established in the study render its future promising for foreseeable and efficient pretreatment under theoretical based experimental design for trace analytes from environmental, biological and clinical samples.

“…Based on previous studies for basic drugs using EME, NPOE solely is a good candidate for SLM in EME. 17 Therefore, NPOE was selected as the optimum organic solvent to provide high recovery for relatively nonpolar PP (log P 2.8). To investigate the effect of carriers, extractions with two types of carriers (i.e., TEHP (neutral carriers) and DEHP (anionic carrier)) as good carriers for SLM in EME were investigated (Fig.…”

Recently, electro-assisted extraction of ionic drugs from biological fluids through a supported liquid membrane and into an aqueous acceptor solution was introduced as a new sample preparation technique and has been termed electromembrane extraction (EME). In the present work, this microextraction technique combined with high-performance liquid chromatography and ultraviolet detection has been developed for detection of phenazopyridine (PP) as a local analgesic drug in human plasma and urine samples. From a 6.5 mL neutral aqueous sample, PP was extracted for 20 min through a thin supported liquid membrane of 2-nitrophenyl octyl ether sustained in the pores of the wall of a porous hollow fiber and into an aqueous acidic acceptor solution (25 L, containing negative electrode) by application of a DC electrical potential. The effects of several factors, including the nature of organic solvent, HCl concentration in donor and acceptor solutions, stirring speed, extraction time, and applied voltage on the extraction efficiency of the drug, were investigated and optimized. Satisfactory linearity ranges with correlation coefficients higher than 0.996 in different extraction media, admissible limits of detection (0.5 and 1.0 ng mL −1 in urine and plasma samples, respectively) and good repeatability and reproducibility (intra-and inter-assay precisions ranged between 3.7%-6.8% and 8.8%-12.5%, respectively) were obtained. The optimized EME procedure was applied to determine the concentration of PP in various matrices, such as plasma and urine samples, and satisfactory results were obtained.Résumé : Une nouvelle technique de préparation d'échantillons à partir de liquides biologiques appelée « extraction électromem-branaire » a récemment fait son apparition. Cette technique consiste à extraire des échantillons par voie électrochimique des médicaments ioniques dans une solution d'extraction aqueuse à travers une membrane liquide sur support. Dans le cadre des présents travaux, nous avons mis au point cette technique de microextraction en association avec la chromatographie liquide à haute performance à détection ultraviolette en vue d'effectuer la détection de la phénazopyridine, un analgésique local, dans des échantil-lons d'urine et de plasma humains. Nous avons utilisé un échantillon aqueux neutre de 6,5 mL pour en extraire la phénazopyridine pendant 20 min à travers une fine membrane liquide de 2-nitrophényloxyoctane supportée par incrustation dans les pores de la paroi d'une fibre poreuse creuse. Les échantillons ont été extraits dans une solution aqueuse acide (25 L, contenant une anode) en appliquant une différence de potentiel pour fournir un courant électrique continu. Nous avons étudié les effets de plusieurs facteurs, notamment la nature du solvant organique, la concentration d'acide chlorhydrique dans les échantillons et les solutions d'extraction, la vitesse d'agitation, le temps d'extraction et le potentiel appliqué, sur le rendement de l'extraction du médicament et avons optimisé ces paramètres. Nous avons obten...

“…SPME has been used for numerous applications, including environmental [14][15][16][17] and biological samples determinations [18][19][20][21]. SPME can be used for either the direct extraction of analytes by exposing the fiber coating to gases or liquid samples, or the indirect extraction from the gaseous headspace above the sample medium [13].…”
